SLEET REMOVER. 1

My invention relates to devices for preventing the accumulation of rain, snow, and sleet on the windshield of. motor vehicles and its purposes are to make a device that shall 5 be cheap in construction, easily and securely applied, and which shall operate elfectively whether the windshield is closed or partially open. I attain these purposes by themeans shown in the accompanying drawings, in ].0 which Figure 1 isa perspective of a part of the front and windshield of an automobile showing the device in position. Figure 2- is a longitudinal view partly in diagram and partly in section showing the interior conl5 struction of the device and Figure 3 is an enlarged perspective view of the device, part of the outer casing being broken away.

Referring more particularly to the drawings, 1 is the main bodygor outer case of my Z 'deVice which is prov ded with removable end braclnts 2 havin flanges 3 adapted to be attaehedin any suitable position, preferably on the framework 4 of the windshield of a motor vehicle.- The case 1 is provided with an opening 5 li avingan outwardly and forwardly extending fiaii'geor, guide 6 me tendingtoward but not quite reaching the windshield when in its closed position. A heating coil; 7 composed preferably of a central core '8 composed of a suitable insulat- 'ing material, having a resistance wire 9 wound spirally around it,-"is' removably mounted in the case and connected by wires 10 and 11 and a suitable switch 12, indi- 35 cated in diagram in Figure 2 but not shown otherwise in the drawings, to a battery or other suitable source 'of electric current 13. The end brackets 2 are providedwith notches and flanges 14 adapted to retain the 40 body 1 in position and the whole is held together by a bolt 15 extending through the center of the core 8.

Application filed April 26, 1926. Serial No.

lV hen it is desired to use the device, the switch 12 is closed, the resistance wire 9 be comes heated and heats the air in the space 16 surrounding the central core which sets up a circulation of warm air flowing outward through the opening 5 and is directed forward by the gui e 6. so that it flows up along the surfaceof the glass. By mounting the device on the frameworkrather than on th'e wind shield itself and by-the use of the flange 6 the device is operated with even more efliciency when the windshield is partly open because the air then strikes against the sloping windshield and flows along it, but in eitlier case it is found by experience that theicurrcnt of heated air inaintains its position close to the glass and thus maintains its purpose of keeping rain, 'sleet, and ice from accumulating on the glass.

- I claim as m y invention and desire to se cure by Letters Patent:

IIIiCOlI'lblDflillOll, a cylindrical outer case having one of its ends removable said ends being provided with flanges adapted to attach to the framework of an automobile, said case having opening and an and inwardly extending flange at one side a longitudinally extending integrally formed outwardly of said opening; a tubular member inounted within said case and having at its errtremities flanges adapted to retain it in concentric position within said case and having a spiral groove on the main body of said member; a bolt extending longitudinal- I 1y through said member and said heads to retain the whole in position, and a resistance coil mounted in said groove and connected by suitable wires to a source of electrical supply.
